2 Claims;

This invention relates to governors and more particularly to a governor for use in controlling the maximum speed of a motor vehicle engine.

An object of this invention is to provide a i; governor which may be readily and quickly interposed between the opposed flanges carried by the carbureter and the intake manifold in an internal combustion engine so as to restrict the passage and thereby control themaximumspeed of the engine.

Another object of this invention is to provide in combination with adevice ofthis kind, means whereby the device may be sealed soas to prevent movement of the governor to a position permitting greater speed of the engine.

A further object of this invention is' to provide a device of this character which is so constructed that it can be stamped out of asheet of metal and readily inserted inoperative posit-ion, thus producing a governor which canbe sold at a. relatively small cost. v

A still further object of this invention, is to provide a device of this character whichis so constructed that when it has once been sealed to maximum speed; the device upon repair of the engine necessitating removal of the carbureter can be removed and replaced in its original position without breaking of the seal and Without changing the position of the device with respect to the fuel passage.

The above and various other objects and advantages of this invention will in part be described in, and in part be understood from the following detail description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a fragmentary side elevation of a carburetor and an intake manifold having a governor constructed according to an embodiment of this invention, interposed therebetween.

Figure 2 is an enlarged sectional view taken on the line 22 of Figure 1.

Figure 3 is a view similar to Figure 2 but showing a modified form of governor.

Referring to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, the numeral it designates generally a carburetor of conventional construction provided with a neck or discharge passage l l and a flange l2 which is secured to the flange 13 at the lower end of an intake manifold M. The two flanges l2 and I 3 are secured together as by bolts 15. This construction is conventional and is here shown as only one type of carbureter and intake manifold construction with (Cl. 13846j which the hereinafter described invention may be combined. I

In order to provide a means whereby thefuel in the form of gases or vapors passing through the neck or outlet passage H may be controlled so as to thereby control the maximum speed of the internal combustion engine associated with the carbureter It, I have provided a governor generally designated as I6; which is interposed between a lower gasket H and an-upper gasket l8 disposed between the confronting faces of the flanges 62 and 53. This governor l'fi comprises a plate I9 having at one edge thereof anotch or slot 29 which opens through the adjacentledge of the plate'so as to receive one of the bolts t5 connecting the two flanges l2 and l3'together. The other side of the plate l9 hasanelongated closed slot 29 of arcuate configuration which loosely receives the other bolt l5 so thatthe plate i9 may be swung with the notched portion 20 as a fulcrum to the limit of the slot 2|.

The plate l9 at a point intermediate the two slots 20 and 2| is provided with a fuel passage or opening 22 which may have a plurality of-bars 23 and 23a, disposed thereacros's so as to prgvi'de an enlarged opening through the plate [9 dependent on the position of the opening 22 with respect to the passage I I.

The plate I9 is also provided with a plurality of spaced apart openings 24 which are disposed adjacent the slot 2| and in selected pairs of these openings 2 there is adapted to be disposed a plate locking or sealing member 25 of substantially U-shaped construction. This sealing member 25 may be made out of wire or like material and the free ends thereof are adapted to be closed or sealed by a lead seal 25, as shown in Figure 1. The wire or sealing member 25 is adapted to engage through the plate 19 at a point on the far side of the opening 22 so as to prevent movement of the plate E9 to a position to thereby enlarge the opening or passage 22 by reason of the relation of this opening 22 with respect to the fuel passage H.

In Figure 3, there is shown a modified form of this governor wherein the plate I9 has a slot 28 to receive one of the bolts l5 and is also provide-d with a closed arcuate slot 2 I The plate 19' has a crescent opening 22 therethrough between the slots 20 and 2! which is adapted to, be moved into register with the fuel passage or pipe II.

The plate I9 is also provided with pairs of holes 24 in selected ones of which a sealing member 25 is adapted to engage so as to prevent movement of the plate I9 beyond the original setting point to prevent speeding up of the internal combustion engine to a point greater than that controlled by the original positioning of the opening 22' with respect to the passage I I.

In the use and operation of this governor, the plate I9 may be inserted or applied to a conventional internal combustion engine construction between the carbureter and the intake manifold by loosening up the bolts I5 and preferably withdrawing only one of these bolts and then slipping the plate I9 between the two flanges I2 and I3 with a gasket I1 and I8 on opposite sides thereof. The removed bolt I5 may then be inserted in the slot 2| with the slot 20 first being disposed about the other flange bolt I5; The engine may then be started and operated in the usual manner whereupon the plate I9 may be swung with one of the bolts I5 as a fulcrum until the maximum speed of the engine is at the desired limit whereupon the locking member 25 is passed through the holes 24 closest to the flanges I2 and I3 on the side of the plate I9 opposite from the opening 22. In other words, the locking member 25 is so positioned that the plate I9 cannot be swung to increase the sides of the orifice but may be swung to decrease the sides of the orifice without disturbing the sealing or looking member 25. After the locking member 25 has been properly positioned in the desired openings 24, the locking member 25 may then be sealed by a conventional lead seal, or the like, and after the position of the locking member 25 has once been determined the carbureter Ill may be detached from the intake manifold and the governor I6 removed for repair to the desired parts of the engine without disturbing the position of the locking member 25. In other words, when a mechanic separates the carbureter I0 from the intake manifold I I by removal of the bolts I5,-the governor l6 may be replaced in its original position in the same manner in which it was first applied and this can be done without disturbing the position of the locking member 25.

The governor I6 may be constructed out of a plate having a fuel passage therethrough and a 15 notch in one edge thereof to receive one of the bolts, said plate having an arcuate slot to loosely receive the other bolt, said slot having as an axis the axial center of said one bolt and said plate being adjustable between the flanges about said one bolt upon loosening of the bolts for the length of said slot, said plate also having a plurality of holes therethrough, and a wire threaded through a pair of said holes and engageable with one side of said flanges to limit the adjustment of the plate in one direction.

2. A governor for an internal combustion engine insertible between the confronting flanges carried by the carbureter and the intake manifold secured together by a pair of bolts, comprising a plate having a fuel passage therethrough and a notch in one edge thereof to receive one of the bolts, said plate having an arcuate slot to loosely receive the other bolt, said slot having as an axis the axial center of said one bolt and said plate being adjustable between the flanges about said one bolt upon loosening of the bolts for the length of said slot, said plate also having a plurality of spaced apart holes extending laterally of said fuel passage, and a wire threaded through a pair of said holes and engageable with one side of said flanges to limit the adjustment of the plate in one direction.
